The matters of the organization of risk management of the heat-supplying organizations (HSO), focused on the increase in the reliability of the heating systems maintenance are considered in the article. The characteristic of the current maintenance conditions of HSO in the countries of the former Soviet Union, which distinction is the existence of some state plans for the change of the heat-supplying industry development financing in the Russian Federation and Uzbekistan, similar in the target orientation. The new methodological-and-methodical approach to the determination of the interrelation between the heating systems maintenance reliability and the risks of HSO with their differentiation according to the significance values, complemented with the classification of risks on the basis of the equilibrium-and-balanced approach and the formation of the matrix for risk analysis is offered as the research result. Due to the purpose of the creation of risk management system in HSO the current state of the information support of their activity, which is recognized insufficient, is studied. The results of the analysis of the interrelation between the reasons of failures during the delivery of heat to consumers because of risks, having constructive, technologic and labour character, and stages of the heating systems lifecycle are presented. Three models of the assessment of the level of engineering structures reliability, depending on the assessment of situation in HSO are offered to the discussion. The risk management system in HSO is considered as an important condition of the reliability assurance, the substantial characteristic of its main components is given.
